FCC RF Exposure EUT Description: ZF954-K4S Remote control Model No.: ZF954-K4S FCC ID: 2BWDOZF954-K4S 1. Limits According to KDB 447498 D01 General RF Exposure Guidance v06 The 1‐g and 10‐g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(max power of channel, including tune‐up tolerance, mW)/(min. test separation distance, mm)]·[√f(GHz)]≤3.0 for 1‐g SAR and ≤ 7.5 for 10‐g extremity SAR, Where: Result=P/D*√F F= the RF channel transmit frequency in GHz P=Maximum turn‐up power in mw D=Min. test separation distance in mm 2. Test Result of RF Exposure Evaluation EIRP(dBm)=83.39(dBuV/m)-95.2=-11.81(dBm) Frequency (MHz) Output power (dBm) Tune Up Power (dBm) Max Tune Up power (mW) Min test separation distance (mm) Result Limit SAR Test Exclusion SRD 433.88 -11.81 -11±1(-10) 0.100 5 0.013 3.0 Pass Note: PK Output power= conducted power. Conducted power see the test report WH-FCC-R26040905, antenna gain = 0dBi Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. The test exclusion threshold is 0.013 which is<= 3, SAR testing is not required. Note: Exclusion Thresholds Results=[(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] f(GHz) is the RF channel transmit frequency in GHz Distance=5mm
